Problem

Four uniform rods made of the same material are listed with their lengths LL and cross-sectional areas AA expressed as multiples of reference values L0L_0 and A0A_0. Each rod has the same temperature difference across its ends. I. L=L0,  A=2A0L = L_0,\; A = 2A_0 II. L=2L0,  A=3A0L = 2L_0,\; A = 3A_0 III. L=0.5L0,  A=0.5A0L = 0.5L_0,\; A = 0.5A_0 IV. L=1.5L0,  A=A0L = 1.5L_0,\; A = A_0 Rank the rods from greatest to least steady-state rate of energy conduction, using only the symbols I–IV. If any rods tie, separate them with an equal sign.
